Belgium fighter ace (1892–1986) during WWI credited with 37 aerial victories. He lost his leg after being wounded by a bullet in 1918, but continued flying until 1940. Glossy 9.25 x 11 photo of Coppens posing in the cockpit of a plane, signed in fountain pen “Willy Coppens de Houthulst,” adding a lengthy aviation-related sentiment in French. In very good condition, with scattered bends and creases, some light surface rubbing, and slight surface loss where the number of victories was scratched out and corrected. RRAuction COA.
